LC Chromatography Columns

Alternative selectivity to alkyl bonded phases, recommended for aromatic groups. Compatible with highly aqueous mobile phases to facilitate the retention and separation of polar compounds.

Brownlee SPP 2.7 µm Phenyl-Hexyl 2.1 X 75 mm

Brownlee SPP 2.7 µm Phenyl-Hexyl 3.0 X 150 mm

Brownlee SPP 2.7 µm Phenyl-Hexyl 3.0 X 30 mm

Solid inner core, porous silica outer shell, shorter diffusion path Very high efficiencies at moderate back pressures Nearly twice the efficiency of 3-µm particle columns As robust as columns packed with 5-µm particles because columns use 2-µm frits
